Expected uncertainty on V<sub>tb</sub> as a function of integrated luminosity.

The expected uncertainty is calculated assuming SM single top cross section. 
This plot is done comparing our previous result for one analysis (matrix element) in summer 2007 with the projections using the combination of three analyses (matrix element, likelihood function and neural network)in winter 2008.

<!-- The improvements in the <a href="http://www-cdf.fnal.gov/physics/new/top/2008/singletop/ME/">new analysis</a>
